    Sorry it seems i was wrong. You do take into account the positron
    No worries man. Thanks for helping me out

    Damn, i thought neutrinos were the same as electrons. I did OCR last year and so we didn't do particle physics

    nah bud! If you're unsure tomorrow theres always the AS data sheet side which says in the top left table that the rest energy of a neutrino is 0MeV, and since 1u = 931.5 MeV, the mass is 0u thats how i check it anyway :L good luck for tomorrow though!

    What will the six marker be on?

    I think it will. There's quite alot to say about it really.
    Lol if that's the six marker the grade boundaries would be tiny. I swear the only information they gave us about Quasars are that they are a radio source, not any implications about that.

    The mass of them is so small that they can be assumed to be negligible
    The mark scheme does take into teh accoutn their mass

    Yeah, I've just looked at it. thanks for letting me know . Best of luck for tomorrow

    Anyone got any revision notes or tips for 'Turning points in physics' paper?

    Yeah it'll probably be on engines or momentum then. It's just I know AQA like :L

    Honestly calculations are hard, easy to miss conversions. Although some questions are just look at the formula booklet, some of them really mess you about. I'd say applied physics is quite hard indeed

    How you finding it?
    I quite like rotational dynamics, lot of calculations. Doubt a flywheel question will come up again. Oh yeah defo, some really odd questions have come up in the past.

    Not too bad, still need to do a couple of papers, afte i memorise nuclear power station safety and all the boring stuff. Should be okay, hoping for an a* overall haha

    What is this derivation of kinetic theory thing? I've never heard of it?

    It's something extremely likely to NOT come up, but it is on the syllabus so technically they can ask it. It's the derivative of one of the formulas.

    Believe in you mate! I need to go over nuclear stuff too. I'm hoping for a B, Phya4 didn't go too well and this is my last exam like!

    I would say it's some brutal experiment relating to Specific heat

    My teacher never mentioned it haha. I'll just have to hope it doesn't come up!

    This is something you'll only ever hear said in an A2 physics thread.

    Someone clearly likes radioactivity as they've just spammed the poll 😂

    Was wondering how it got to 100 so fast
    Some AQA examiner that's trying to fool us

    imo the SHC experiments are quite straight forward

    Someone clearly has either:

    a) no life
    b) lost the plot and is prioritising spamming a poll over their A level physics grade
    c) all of the above
